Trying to make a script or handler for closing the map

[Houdiniii 0]

I'm very new to scripting arma and only have some programming experience.
I'm trying to make a handler that closes the map if a player opens it so I can force them to use the alternative cTab mod while I can still open it(Zeus).

I've tried to put this into their playable characters init:
 

this addEventHandler["Map", { params ["_mapIsOpened", "_mapIsForced"];openMap false;}];

But failed and since I don't really know how to manage the debug console or even open it I turned to the forums, any help is highly appreciated and feel free to ask questions!

addMissionEventHandler ["Map", { params ["_mapIsOpened", "_mapIsForced"]; }];
